Clementine 1 - .
Payload: Clementine 1 / DSPSE-ISA [Star-37FM]. Mass: 424 kg (934 lb). Nation: USA. Agency: BMDO. Class: Moon. Type: Lunar probe. Spacecraft: Clementine. USAF Sat Cat: 22973 . COSPAR: 1994-004A. Apogee: 409,890 km (254,690 mi). Perigee: 804 km (499 mi). Inclination: 63.8000 deg. Period: 16,158.80 min. SDIO sensor technology demonstration; mapped lunar surface; planned asteroid flyby cancelled due to spacecraft failure. After two Earth flybys, lunar insertion was achieved on February 21. Lunar mapping took place over approximately two months, in two parts. The first part consisted of a 5 hour elliptical polar orbit with a perilune of about 400 km at 28 degrees S latitude. After one month of mapping the orbit was rotated to a perilune of 29 degrees N latitude, where it remained for one more month. This allowed global imaging as well as altimetry coverage from 60 degrees S to 60 degrees N. After leaving lunar orbit, a malfunction in one of the on-board computers on May 7 at 14:39 UTC (9:39 AM EST) caused a thruster to fire until it had used up all of its fuel, leaving the spacecraft spinning at about 80 RPM with no spin control. This made the planned continuation of the mission, a flyby of the near-Earth asteroid Geographos, impossible. The spacecraft remained in geocentric orbit and continued testing the spacecraft components until the end of mission. Additional Details: here....
